How to Disable Private Browsing in Firefox.
Firefox web browser offers the ability to browse privately, which disables the ability to store web activity, such as cookies, and browsing history. This allows the user to browse the web without leaving any traces of their activity and locally stored information or data that can be retrieved later.
Firefox Private browsing is also called incognito browsing or privacy mode, because it prevents Firefox from storing data about the user's activity (e.g. searches, browsing history, etc.), deleting all such data after closing all private windows. To browse the web in incognito mode with Firefox, press Ctrl + Shift + P keys, or go to Firefox's menu and select New Private window. *
* Note: Please note that "private browsing" does not imply that your online activities are completely private, because it does not hide your identity from the websites you visit or your browsing behavior from your internet service provider (ISP).
Why Disable Firefox Incognito Browsing Mode?
Although Firefox's Private Browsing feature is a good practice to prevent others from seeing and learning information about your online activity, especially when sharing your computer with others or when using public computers (e.g. in Internet cafes), on the other hand you may want to prevent someone under your supervision (e.g. your children) from hiding their activity from you.
